ALV Print Problem:Please Help

Dear Friends,

I've been executing an ALV of Group-wise Customer Ageing. The display of this ALV comes OK, but when I print it, the print comes one customer group per page, for example if a customer group contains even only one customer it'll printed on a seperate page following others. This is resulting in unnecessary wastage of pages. I want all the customer groups one after other on a single page (as a normal print) together as per the display of ALV.
